[0045] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0046] (1) SMTC

[0047] NR introduces a set of configuration information of measurement time windows for SSB measurements, namely SMTC. Usually, the SMTC configuration contains information such as the period (periodicity), position (offset) and length (duration) of the time window. SMTC is configured separately for each frequency point. A set of SMTC information is configured on each measurement frequency point. The UE can determine the measurable time window of the corresponding frequency point based on this information. In order to match the different SSB periods of different cells, this restriction was subsequently relaxed. It can be allowed to configure two SMTCs on the same frequency point. For example, a denser (i.e., smaller period, but the same position and length) SMTC is configured for the same-frequency measurement frequency point to measure the service cell and the specific cell, thereby speeding up the measurement. Specifically, the cell measured by the SMTC can be indicated by a list, which is the PCI list (pci-List) associated with the SMTC in the SMTC information element (SSB-MTC information element).

[0048] The SMTC configuration in NTN is more complex. Considering the long propagation distance from satellite to UE and the fact that the propagation distances of different satellites may vary greatly, the time it takes for the reference signal SSB sent by the satellite to reach the UE may not be measured by a single SMTC for all satellites. Therefore, multiple SMTCs are also introduced in NTN (the newly introduced SMTC is denoted as SSB-MTC4). The periods and lengths of multiple SMTCs are the same, only the locations differ. In addition, each SMTC is also associated with a list (e.g., pci-List), which indicates the ID (identifier) ​​of the target cell measured by the SMTC.

[0049] Currently, in the NTN system, up to four SMTCs can be configured per frequency band, including one legacy SSB-MTC and up to three SSB-MTC4s. Since the location of each SSB-MTC4 is based on the assumption that the service link propagation delay difference between the serving cell and the neighboring cell is equal to 0ms (milliseconds), but in reality there is a propagation delay difference between the serving cell and the neighboring cell, the UE can adjust the actual offset based on the actual propagation delay difference. In the RRC (Radio Resource Control) connected state, the network can obtain the UE's location information and calculate the propagation delay based on the distance between the UE and the cell (satellite) to be measured, thereby configuring or updating the accurate SMTC offset value. In the RRC idle (IDLE) / inactive state, the UE has not yet connected to the network, and the network cannot obtain the UE's location information in real time. Therefore, the UE is allowed to determine the SMTC offset value based on the actual propagation delay.

[0050] (2) Impact of SMTC on measurement time

[0051] Compared to terrestrial networks (TNs), configuring multiple SMTCs in an NTN affects the time required to measure neighbor cells. Taking the same frequency as an example, the time required to detect, measure, and evaluate neighbor cells in the idle / inactive state is shown in Table 1.

[0052] Table 1

[0053] On this basis, the scaling factor K is also introduced multi_SMTC , for example, the detection time is T in Table 1 detect,NR_Intra Multiply by K multi_SMTC The measurement and evaluation times are similar.

[0054] K multi_SMTC is the scaling factor for measurements of multiple SMTCs corresponding to different satellites.

[0055] In the case where multiple SMTCs do not overlap, if the GEO satellite is measured on the carrier, K multi_SMTC =1; if the LEO satellite is measured on the carrier, then

[0056] In the case where multiple SMTCs partially overlap, if only GEO is measuring on the carrier, then K multi_SMTC =N SMTC，overlap ; If only LEO satellites are measured on the carrier, then

[0057] Among them, N LEO,i is the number of LEO satellites measured in the i-th SMTC; N LEO,simul N is the number of LEO satellites that the UE can measure in parallel within one SMTC; SMTC，overlap is the number of SMTCs that partially overlap with each other.

[0058] As explained above, when measuring neighboring cells in the NTN system, in order to ensure that the SMTC can follow the movement of the associated satellite, the UE can adjust the actual offset according to the propagation delay difference of the satellite, that is, adjust the position of the SMTC. However, when an SMTC window is associated with multiple satellites, the different mobility characteristics of the multiple satellites may result in different offsets of the measurement window, that is, the SMTC offset direction or step size may be different. For example, when an SMTC window is associated with multiple satellites, it is unclear in which direction the SMTC window is offset in the time domain. As shown in Figure 2, if two satellites Sat1 and Sat2 are on the same carrier and an SMTC configuration is configured on the carrier, but Sat1 and Sat2 move in opposite directions, the direction of the SMTC window offset is unclear, or it is impossible to satisfy the measurement of Sat1 and Sat2 based on the same offset.

[0059] Based on this, it is necessary to consider how to adapt to the different mobility characteristics of different satellites or related cells for measurement when one SMTC is associated with multiple satellites.

[0060] FIG3 is a schematic flow chart of a measurement adjustment method according to an embodiment of the present application. The method can optionally be applied to the system shown in FIG1 , but is not limited thereto. The method includes at least part of the following contents.

[0061] S310: If a first condition is met, the terminal device adjusts SMTCs used for measuring multiple satellites or cells and / or first information corresponding to the SMTCs, wherein the first condition is related to the multiple satellites or cells, and the adjustment includes autonomous adjustment by the terminal device or adjustment based on network configuration.

[0062] The SMTC in step S310 is used for the measurement of multiple satellites or cells. In some embodiments, the SMTC is used for the measurement of multiple satellites, that is, the SMTC is associated with multiple satellites. In other embodiments, the SMTC is used for the measurement of multiple cells, that is, the SMTC is associated with multiple cells, wherein the cell and the satellite have a mapping relationship, that is, the cell is a cell in the NTN system, and its network equipment may include a satellite. Exemplarily, the mapping relationship between the cell and the satellite can be one-to-one, many-to-one or one-to-many, that is, the mapping relationship between the cell and the satellite can be one cell corresponding to one satellite, two or more cells corresponding to the same satellite, or one cell corresponding to multiple satellites. It can be understood that since there is a mapping relationship between the cell and the satellite, the problem of not being able to perform measurements based on the same SMTC offset as described above also exists when multiple cells are associated with the same SMTC.

[0063] In some embodiments, the first condition may be related to the mobility characteristics of multiple satellites or cells (i.e., multiple satellites or multiple cells), such as the direction of movement and the speed of movement. Alternatively, the first condition may be related to the indication / configuration of the network device for multiple satellites or cells, wherein the network device may also indicate / configure the mobility characteristics of multiple satellites or cells. For example, the first condition may be a condition for characterizing that multiple satellites or cells cannot all be measured in the above-mentioned SMTC or cannot be measured based on the same offset value of the SMTC.

[0064] According to the above method, when the first condition is met, the terminal device adjusts the SMTC used for measuring multiple satellites or cells or the first information corresponding to the SMTC, thereby overcoming the problem that when multiple satellites or cells are associated with the same SMTC, it is impossible to perform measurements based on the same SMTC or the same SMTC offset, which is conducive to realizing measurements adapted to the mobility characteristics of different satellites.

[0065] According to the above embodiment, the terminal device can adjust the SMTC used for measuring multiple satellites or cells. Optionally, the terminal device can adjust the SMTC used for measuring multiple satellites or cells from a first SMTC to a second SMTC. Or, if multiple satellites or cells are associated with the first SMTC, the terminal device can switch satellites or cells among the multiple satellites or cells that cannot be measured in the first SMTC to the second SMTC for measurement. In other words, the terminal device can switch between multiple configured SMTCs for all or some of the multiple satellites or cells.

[0066] In some embodiments, the terminal device may also adjust the first information of the SMTC, wherein the first information includes one or more of the following information:

[0067] SMTC configuration information;

[0068] When measuring the first satellite or the first cell, the offset value of the SMTC;

[0069] One or more satellites or cells associated with the SMTC;

[0070] The satellite or cell to be measured among the multiple satellites or cells associated with the SMTC.

[0071] Exemplarily, the first information may include configuration information of the SMTC. That is, the terminal device may adjust the configuration information of the SMTC used to measure multiple satellites or cells. Optionally, the configuration information may include at least the SMTC period and / or the SMTC length. Specifically, the association relationship between multiple satellites or cells and the SMTC may be maintained, and the configuration information of the SMTC may be adjusted. For example, assuming that 4 SMTCs are pre-configured, including 1 traditional SMTC and 3 SSB-MTC4s, wherein the second SSB-MTC4 is associated with multiple satellites or cells; when the first condition is met, multiple satellites or cells are still associated with the second SSB-MTC4, but the configuration information of the second SSB-MTC4 can be adjusted.

[0072] Exemplarily, the first information may include an offset value of the SMTC when measuring the first satellite or the first cell. The first satellite may be one of the multiple satellites mentioned above, and the first cell may be one of the multiple cells mentioned above. That is, the terminal device may adjust / switch the offset value when measuring a certain satellite or a certain cell based on the same SMTC associated with multiple satellites or cells. Exemplarily, the terminal device may use different offset values ​​for different satellites or different cells. This method can be regarded as maintaining the association relationship between multiple satellites or cells and the SMTC, and adjusting the secondary association relationship between each satellite or cell and the SMTC offset value.

[0073] Exemplarily, the first information may include one or more satellites or cells associated with the SMTC. That is, the terminal device may adjust one or more satellites or cells associated with the SMTC on the basis that multiple satellites or cells are associated with the same SMTC. For example, one or more satellites are deleted from the satellite list associated with the SMTC, or one or more cells are deleted from the cell list associated with the SMTC; wherein the deleted satellite or cell may be a satellite or cell whose reference signal deviates from the SMTC beyond a threshold, or a satellite or cell whose reference signal measurement result (such as RSRP and / or RSRQ, etc.) exceeds a measurement threshold. Accordingly, one or more satellites in the satellite list associated with other SMTCs may be added to the satellite list associated with this SMTC, or one or more cells in the cell list associated with other SMTCs may be added to the cell list associated with this SMTC. This method can be regarded as adjusting the association relationship between the SMTC and the satellite or cell.

[0074] For example, the first information may include a satellite or cell to be measured among multiple satellites or cells associated with the SMTC. The satellite to be measured is the satellite actually measured, and the cell to be measured is the cell actually measured. That is, the terminal device can adjust the satellite or cell actually measured among the multiple satellites or cells associated with the SMTC, for example, measuring only high-priority satellites or cells, or measuring only those satellites or cells that match the SMTC.

[0075] It should be noted that the first information may also include a combination of two or more of the above information. For example, the first information includes the configuration information of the SMTC and one or more satellites or cells associated with the SMTC. In other words, both the configuration information of the SMTC and the association relationship between the SMTC and the satellite or cell are adjusted. The embodiment of the present application does not limit the manner in which the above information is combined. In actual applications, it can be flexibly set according to scenario requirements, protocol agreements, or system agreements, and they are not listed one by one here.

[0076] According to the above embodiment, the terminal device can adopt one or more adjustment methods to adapt to the different moving directions and speeds of multiple satellites, thereby improving the flexibility of adjustment and ensuring that the terminal device completes the measurement.

[0077] In some embodiments, the measurement adjustment method may further include: the terminal device determines whether the first condition is met by detecting relevant information of multiple satellites or cells; and / or the terminal device determines whether the first condition is met based on second information received from the network device.

[0078] In other words, the first condition may be related to the terminal device's autonomous detection results of multiple satellites or cells, such as the terminal device's detection results of the moving direction, speed, ephemeris position, or SSB of the multiple satellites or cells. Alternatively, the first condition may be related to second information sent by the network device for the multiple satellites or cells, such as ephemeris information broadcast by the network device or instruction information or configuration information sent by the network device.

[0079] In some embodiments, the first condition includes a dynamic SMTC switching condition. Specifically, the first condition may be a dynamic SMTC switching condition pre-agreed in the system or agreed upon in a protocol, and the terminal device may directly determine whether to adjust the SMTC or the corresponding first information based on the pre-agreed dynamic SMTC switching condition without paying attention to the specific condition setting.

[0080] In some embodiments, the first condition may include at least one of the following:

[0081] The terminal device detects that multiple satellites or cells are operating out of sync;

[0082] The terminal device detects different speeds of multiple satellites or cells;

[0083] The terminal device detects a change in the ephemeris position transmission of at least one of the plurality of satellites or cells;

[0084] The terminal device cannot detect the SSB of at least one of the multiple satellites or cells;

[0085] The terminal device determines, based on the ephemeris information in the received broadcast information, that at least one of the plurality of satellites or cells cannot be measured based on the SMTC;

[0086] The terminal device receives first indication information from the network device, where the first indication information is used to instruct the terminal device to adjust SMTCs and / or first information corresponding to the SMTCs used for measurement of multiple satellites or cells.

[0087] It should be noted that the at least one of the above-mentioned multiple satellites or cells refers to one or more of the multiple satellites, or one or more of the multiple cells.

[0088] Exemplarily, the first condition may include the terminal device detecting that multiple satellites or cells are operating asynchronously or at different speeds or that the ephemeris position of at least one of the multiple satellites or cells has changed. In this way, the terminal device can determine that at least one of the multiple satellites or cells cannot be measured in the currently configured SMTC, that is, multiple satellites or cells cannot all be measured in the currently configured SMTC. The terminal device can then adjust the SMTC used for measuring the multiple satellites or cells or the first information corresponding to the SMTC so that the terminal device can adaptively complete the measurement.

[0089] For example, the first condition may include that the terminal device cannot detect the SSB of at least one of the multiple satellites or cells. In this way, the terminal device can determine that at least one of the satellites or cells cannot be measured, and the terminal device can adjust the SMTC or the first information corresponding to the SMTC.

[0090] Exemplarily, the first condition may include the terminal device determining, based on ephemeris information in received broadcast information, that at least one of the multiple satellites or cells cannot be measured based on the SMTC. For example, the terminal device infers, based on the ephemeris information, that a propagation link change has caused one or more satellites to be ineligible for measurement within the currently configured SMTC. In other words, the terminal device can confirm whether multiple satellites or cells all meet the requirements for measurement within the currently configured SMTC based on information sent by the network device, without having to confirm whether multiple satellites or cells all meet the requirements for measurement within the currently configured SMTC through self-detection.

[0091] Exemplarily, the first condition may include the terminal device receiving first indication information from the network device, where the first indication information is used to instruct the terminal device to adjust the SMTC and / or the first information corresponding to the SMTC used for measuring multiple satellites or cells. In other words, the terminal device may adjust the SMTC and / or the first information corresponding to the SMTC based on the indication or configuration of the network device. The first indication information may be sent by the network device when it determines that multiple satellites or cells cannot all be measured in the currently associated SMTC.

[0092] It should be noted that the first condition may also include a combination of two or more of the above conditions. For example, the first condition may include that the terminal device detects that multiple satellites or cells are operating asynchronously, and the terminal device receives a first indication message. In this case, the terminal device needs to adjust the SMTC or the corresponding first information when it detects that multiple satellites or cells are operating asynchronously and the network device has indicated it. The embodiment of the present application does not limit the way the above conditions are combined. In actual applications, they can be flexibly set according to scenario requirements, protocol agreements, or system agreements, and are not listed here one by one.

[0093] Optionally, the first condition can be set separately according to the RRC state of the terminal device.

[0094] Specifically, in some embodiments, when in the idle state or the inactive state, the first condition includes at least one of the following:

[0095] The terminal device detects that multiple satellites or cells are operating out of sync;

[0096] The terminal device detects different speeds of multiple satellites or cells;

[0097] The terminal device detects a change in the ephemeris position of at least one of the plurality of satellites or cells;

[0098] The terminal device cannot detect the SSB of at least one of the multiple satellites or cells;

[0099] The terminal device determines, based on the ephemeris information in the received broadcast information, that at least one of the multiple satellites or cells cannot be measured based on the SMTC.

[0100] That is, when in an idle state (IDLE) or an inactive state (inactive), the terminal device can determine whether the first condition is met by actively detecting or broadcasting ephemeris information from the network to determine whether to adjust the SMTC or the corresponding first information. Accordingly, the terminal device can make autonomous adjustments. For example, the terminal device can make adjustments based on the actual propagation delay. In this way, the terminal device can adapt to the mobility characteristics of multiple satellites or cells for measurement even in the RRC IDLE / inactive state.

[0101] In some embodiments, when in the connected state, the first condition includes at least one of the following:

[0102] The terminal device detects that multiple satellites or cells are operating out of sync;

[0103] The terminal device detects different speeds of multiple satellites or cells;

[0104] The terminal device detects a change in the ephemeris position of at least one of the plurality of satellites or cells;

[0105] The terminal device cannot detect the SSB of at least one of the multiple satellites or cells;

[0106] The terminal device determines, based on the ephemeris information in the received broadcast information, that at least one of the plurality of satellites or cells cannot be measured based on the SMTC;

[0107] The terminal device receives first indication information from the network device, where the first indication information is used to instruct the terminal device to adjust SMTCs and / or first information corresponding to the SMTCs used for measurement of multiple satellites or cells.

[0108] That is, when in a connected state, the terminal device can determine whether the first condition is met through active detection, or ephemeris information broadcast by the network, or an instruction from the network, to determine whether to adjust the SMTC or the corresponding first information. Accordingly, the terminal device can make adjustments autonomously or based on the instructions / configuration of the network device. Optionally, the first indication information sent by the network device can be determined based on the location information of the terminal device.

[0109] According to the above embodiment, in the RRC connected state, since the network device can obtain the location information of the UE and calculate the propagation delay according to the distance between the UE and each satellite or cell, the SMTC or the corresponding first information can be more accurately configured or updated.

[0110] In some embodiments, the first indication information includes one or more of the following information:

[0111] SMTC configuration information;

[0112] The relationship between the offset value and the satellite or cell;

[0113] The relationship between SMTC and satellite or cell;

[0114] The adjusted SMTC is used to measure a second satellite or a second cell among the multiple satellites or cells;

[0115] The priority of a third satellite or a third cell among the multiple satellites or cells.

[0116] Exemplarily, the first indication information may include SMTC configuration information. Here, the SMTC configuration information may include one or more of the adjusted SMTC length, period, and position (offset), or one or more of the target length, target period, and target position. Accordingly, the terminal device may adjust the SMTC configuration information for multiple satellite or cell measurements based on the first indication information.

[0117] Exemplarily, the first indication information may include an association relationship between an offset value and a satellite or cell. Specifically, the first indication information may include an SMTC offset value for a single satellite or cell, i.e., the network device may configure the terminal device to maintain an association relationship between multiple satellites or cells and SMTC, and adjust a secondary association relationship between each satellite or cell and the SMTC offset value.

[0118] Exemplarily, the first indication information may include an association relationship between an SMTC and a satellite or cell. That is, the network device may configure the terminal device to adjust the association relationship. Specifically, the first indication information may indicate one or more satellites or cells associated with the SMTC, or indicate that multiple satellites or cells are associated with other SMTCs. In this way, the terminal device may adjust the SMTCs used for associating multiple satellites or cells, or adjust one or more satellites or cells associated with the SMTC, based on the first indication information.

[0119] Exemplarily, the first indication information may include an adjusted SMTC for measuring a second satellite or a second cell among multiple satellites or cells. The second satellite may be any one of the multiple satellites, and the second cell may be any one of the multiple cells. Specifically, the first indication information may instruct the terminal device to adjust the satellite or cell that cannot be measured by the current SMTC to be measured based on other SMTCs, i.e., to adjust one or more associated SMTCs among the multiple satellites or cells.

[0120] Exemplarily, the first indication information may include the priority of a third satellite or a third cell among the multiple satellites or cells. The third satellite may be any one of the multiple satellites, and the third cell may be any one of the multiple cells. Optionally, the first indication information may indicate the priority of each of the multiple satellites or cells associated with the SMTC. In this way, the terminal device may determine the satellite or cell to be measured based on the first indication information.

[0121] It should be noted that the first indication information may also include a combination of two or more of the above information. For example, the first indication information may include the configuration information of the SMTC and the priority of each satellite or each cell. The terminal device can then adjust the configuration information of the SMTC and determine the satellites or cells that need to be measured (only measure these satellites or cells). The embodiment of the present application does not limit the manner in which the above information is combined. In actual applications, it can be flexibly set according to scenario requirements, protocol agreements, or system agreements, and they are not listed here one by one.

[0122] As described above, the terminal device can autonomously adjust or adjust the satellites or cells to be measured among multiple satellites or cells according to the instructions / configuration of the network device, for example, only measuring high-priority satellites or cells, or only measuring satellites or cells that can match the associated SMTC. In some embodiments of the present application, the measurement time can also be adjusted according to the number of satellites or cells to be measured. Specifically, in some embodiments, the measurement adjustment method can also include:

[0123] The terminal device determines the number of satellites to be measured or cells to be measured among the multiple satellites or cells based on the first information;

[0124] The terminal device determines the measurement time based on the quantity;

[0125] The terminal device measures the satellite to be measured or the cell to be measured according to the measurement time.

[0126] The measurement time can be a measurement window length determined based on the measurement sampling requirements, SMTC period, number of measurement objects, number of SMTCs, etc., such as T in the aforementioned related art. measure,NR_IntraAccording to an embodiment of the present application, the terminal device can adjust the satellites to be measured or the cells to be measured, and based on this, determine the measurement time according to the number of satellites to be measured or the cells to be measured (for example, determine the measurement time according to the number and the adjusted SMTC-related information), and measure the satellites or cells to be measured based on the measurement time, rather than measuring all satellites or cells associated with the SMTC. In this way, the measurement time requirement of the terminal device can be met.

[0127] In some other embodiments, the measurement adjustment method may further include:

[0128] The terminal equipment increases the measurement time of multiple satellites or cells;

[0129] The terminal device measures multiple satellites or cells based on the first information and the measurement time.

[0130] For example, the terminal device can increase the measurement time of multiple satellites or cells by increasing the correlation coefficient in the measurement time calculation (for example, the coefficient M related to the SMTC configuration in the aforementioned related art). By extending the measurement time and measuring multiple satellites or cells, the measurement time requirement of the terminal device can be met.

[0131] To facilitate understanding of the above technical solution, application examples of the embodiments of the present application are provided below for different RRC states.

[0132] Application Example 1

[0133] This application example is for the dynamic switching of SMTC in IDLE or inactive state. Specifically, the triggering conditions for dynamic switching of SMTC in IDLE or inactive state include:

[0134] 1. If the UE detects that multiple satellites or cells associated with an SMTC are operating out of sync or at different speeds, or their ephemeris positions have changed, or;

[0135] 2. The UE detects that a "dynamic SMTC switching" condition is met (the "dynamic SMTC switching" is, for example, that the SSB of a satellite that should have been detected cannot be detected), or

[0136] 3. The UE receives the broadcasted satellite ephemeris information and infers that the propagation link changes cause some satellites to not meet the measurement requirements in the currently configured SMTC.

[0137] It should be understood that, in some embodiments, the difference between a UE in an IDLE or inactive state and a UE in a connected state is that a UE in an IDLE or inactive state can adjust the SMTC offset on its own and cannot receive a remeasurement configuration from the network.

[0138] When a UE that meets the above trigger conditions measures multiple satellites or cells, the UE's measurement behavior may be:

[0139] 1. The UE switches the SMTC configuration of the measurement satellite / cell (including at least the SMTC length and period) according to the association between the satellite or cell ID in the measurement configuration and the SMTC configuration, and meets the adjusted measurement time requirements. Or,

[0140] 2. The UE adjusts / switches the association in the measurement configuration to the SMTC offset used for actual measurement of the satellite or cell ID under the same SMTC. The offset in the association can be a pre-configured enumeration value such as +5ms, +3ms, -3ms, -5ms, or an empirical value recommended by the network or UE. After switching the association, the UE continues to use the SMTC and offset to perform measurements on the satellite / cell and meets the adjusted measurement time requirements. Or,

[0141] 3. The UE adjusts or switches the association of satellite or cell IDs under the SMTC in the measurement configuration, adding or removing some satellites or cells, such as cells or satellites whose offset exceeds the threshold or exceeds a certain RSRP measurement threshold. After the association adjustment or switch, the UE continues to use the SMTC and offset to perform the updated associated measurement satellites / cells and meet the adjusted measurement time requirements.

[0142] Among them, measurement time requirements may include:

[0143] 1. The UE only measures the measurement time required by the satellites or cells with high priority or matching the SMTC.

[0144] 2. The UE should measure all associated satellites or cells as much as possible, which can be achieved by extending the measurement time.

[0145] Application Example 2

[0146] This application example is for dynamic SMTC switching in the connected state. Specifically, in the connected state, if the UE receives network configuration signaling (such as the first indication information in the above embodiment, which can be an SMTC switching instruction or a measurement cell / satellite priority indication), or if the UE meets the triggering conditions in the above application example 1, SMTC dynamic switching can be performed.

[0147] The SMTC parameters configured or reconfigured by the network include at least one of the following:

[0148] 1. MTC offset, and / or SMTC length, and / or SMTC period;

[0149] 2. The relationship between SMTC and cells or satellites;

[0150] 3. Secondary association between SMTC offset and cell or satellite;

[0151] 4. For satellites or cells that cannot be measured in the currently associated SMTC, the switched SMTC is configured, that is, these satellites or cells are measured in the switched SMTC (equivalent to configuring or reconfiguring the association relationship);

[0152] 5. Measurement priority of cell or satellite.

[0153] When the UE receives the signaling configured by the network or the UE meets the triggering conditions in the above application example 1, the UE's measurement behavior may be: when the UE measures multiple satellites, it determines which satellites / cells to measure based on the adjusted SMTC parameter 1, or the switched SMTC or SMTC offset association relationship (parameters 2-4), or the measurement priority (parameter 5), and meets the adjusted measurement time requirements.

[0154] The measurement time requirement may be a time requirement for measuring only high-priority or designated associated cells / satellites, or a measurement time requirement for measuring all configured satellites or cells (the time is longer than before adjustment and may be lengthened according to a scaling factor).

[0155] For example, the UE's measurement behavior may include:

[0156] 1. When the UE receives the signaling configured by the network or the triggering condition in application example 1 is met, the UE adjusts the SMTC configuration (including at least the SMTC length and period) of the measurement satellite / cell according to the reconfigured SMTC offset, and / or SMTC length, and / or SMTC period, and meets the adjusted measurement time requirements. Or,

[0157] 2. When the UE receives the signaling from the network configuration or meets the triggering conditions in Application Example 1, the UE switches the SMTC configuration of the measurement satellite / cell (including at least the SMTC length and period) according to the association between the reconfigured satellite or cell ID and the SMTC configuration, and meets the adjusted measurement time requirements. Or,

[0158] 3. When the UE receives the signaling configured by the network or the triggering condition in the application example 1 is met, the UE adjusts / switches the SMTC offset used for actual measurement of the satellite or cell ID associated with the same SMTC in the measurement configuration according to the association relationship between the reconfigured SMTC offset and the cell or satellite. After the association relationship is switched, the UE uses the SMTC and the new offset to perform the measurement of the satellite / cell and meets the adjusted measurement time requirement. Or,

[0159] 4. When the UE receives signaling configured by the network or the triggering conditions in Application Example 1 are met, the UE adjusts the satellites / cells that cannot be measured in the currently associated SMTC and switches to other configured SMTCs for measurement (switching associations), such as adding or deleting some satellites or cells (such as cells or satellites whose offset deviation exceeds a threshold or exceeds a certain RSRP measurement threshold). After adjusting or switching the association, the UE continues to use the SMTC and offset to perform the updated associated measurement satellites / cells and meets the adjusted measurement time requirements.

[0160] As can be seen, the embodiment of the application provides a measurement adjustment method, which includes a SMTC dynamic adjustment scheme and, optionally, a scheme for determining the corresponding measurement time. Based on the method of the embodiment of the application, it is possible to adapt to the mobility characteristics of multiple satellites or cells for measurement.
